The Foundation of HAM is significantly involved in the preservation of the DAKOTA propeller of the Gauli
On 19. november 1946 “beached” a Douglas C-53 of the American armed forces on the Gauli in the Bernese Oberland. How miraculously all occupants survived the violent impact, was the machine with a speed of approximately 280 km/h on the road. What followed was a major, multi-day search and rescue operation. It succeeded Swiss pilots with small airplanes of type FIESELER STORCH to land on the glacier and nine flights to fly the victim in the Valley. This Act is regarded as birth of the alpine air ambulance. The wreckage of the plane remained for the most part on the glacier, was snowed in and sank gradually into the ice.
